68x+216=0
Pahekotia te 100x me -32x, ka 68x.
68x=-216
Tangohia te 216 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-216}{68}
Whakawehea ngā taha e rua ki te 68.
x=-\frac{54}{17}
Whakahekea te hautanga \frac{-216}{68} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
